MACHINE FOR MAKING HAT LININGS.

Original application filed September 29, 1921, Serial No. 504,094. Divided and this application filed October 13, 1922.

,T 0 all whom it may concern.

Be it known that I, RUDOLPH BECKER, a citizen of the United States, residing at North Plainfield, in the county of Somerset and State of New Jersey, have invented certain new and useful Improvements in Machines for Making Hat Linings, of which the following is a specification, reference being had therein to the accompanying drawings.

Machines for making hat linings commonly comprise a sewing machine with which is associated a work-support in the form of a turn-table rotatable about a shifting center and serving as a support for the hat lining, whereby such lining is so presented to the needle of the sewing machine that the stitches are laid in an elliptical path approximating the shape of the crown of a hat. It is also customary to associate a cutting machine with the turn-table and provide for the moving of the turntable from the sewing machine to the cutting machine to effect the trimming off of the surplus material outside of the line of stitches.

The cutting machine commonly comprises a pair of continuously rotating disks mounted on parallel shafts placed one above the other and turning in opposite directions, the edges of the disks overlapping so as to cut with a shearing action. The continuous running of the cutting machine wastes power, since it is only needed at intervals between sewing operations, and manual control of the starting and stopping of the cutting machine would add to the burdens of the operator and prevent the attainment of maximum production.

An object of the present invention, therefore, is to provide for the automatic control of the starting and stopping of the cutting machine so that it will run only when needed and will not be consuming power when not needed.

According to the present improvement, in its preferred embodiment, the starting and stopping means for the cutting mechanism is connected to be controlled by the shifting of the turn-table from the sewing machine to the cutting machine. The starting and stopping means is preferably connected to a contrOHQVfil W ieh a e ies 1. .1 9 th path of Serial No. 594,284.

movement of the turn-table support so that when the latter is shifted to carry the work from sewing to cutting position, a cam-edge on such support engages and shifts the control-lever and thus causes the cutting machine to start. When the turn-table is returned to sewing position, a spring restores the control-lever to stopping position.

The turn-table support may be equipped with any well known turn-table mechanism for elliptical stitching. I prefer, however, to use the turn-table mechanism disclosed in my copending application Serial No. 504,094, filed Sept. 29, 1921, of which this application is a division.

The invention will be understood from the accompanying drawings and the following detailed description of a machine which em bodies the invention in a form suitable for sewing hat linings.

In the drawings, Fig. 1 is a view of a complete outfit embodying the invention and Fig. 2 a plan view showing the controlling lever for the cutting mechanism.

The complete machine embodying the invention and adapted for sewing hat linings comprises three units associated on a suitable support 1; such units comprising a sewing machine 2, a cutting machine 3, and a work-carrier or turn-table support 4 which latter is pivoted at 5 to the support 1 so that it may swing about its pivot from full line or sewing position adjacent the sewing machine, Fig. 1, to dotted line or cutting position adjacent the cutting machine 3 and vice versa.

The sewing machine may be of any suitable type such, for example, as the well known Singer Class 246O chain stitch machine having the usual stitch-forming and feeding mechanisms including the reciprocating needle 6, rotary looper 7 and presser-foot 8 with which the usual fourmot-ion feed-dog (not shown) cooperates to feed the work.

The cutting mechanism is of the usual construction and comprises the upper and lower shafts 9 and 10 which are rotated in opposite directions by suitable connections with the tight belt-pulley 11 alongside of which is mounted the loose. pulley 12 to receive the belt when the cutting mechanism is idle The shafts 9 and 10 carry the cutter-wheels 13 and 14 whichare associated in the usual manner with their peripheral portions in overlapping relation so as to cut with a shearing action; In the present instance, a belt=guicle 15 is mounted toslide horizontally in suitable supports 16, 17 on the frame; said guide carrying a collar 18 and a spring 19 interposed between the latter and the bearing support 17 and serving to urge" the belt-guide to stopping position or toward the loose pulley 12. The belt-guide has secured to it a split head 20 which receives the end of a lever 21. The head 20 carries a pin 20" entering the slot 21"i11 the lever 21; said lever being pivoted at 22 to the base 23 of the cutting mechanism and at its other end carrying a roller 24: which is positioned in the path of movement of the cam-plate 25 mounted on the work-carrier 4. The cam-plate 25 has an inclined portion 26 and a portion 27 which is concentric withthe pivot 5. g

It will be evident that when the workcarrieris in sewing or full line position, Fig. 1, the cutting mechanism willbe stationary since the spring 19 will hold the belt on the pulley 12. When the work carrier 4 is shifted to cutting position, however, the inclined edge 26 of thecam-plate 25 will encounter the roller 24 and rock the lever 21, thereby effecting the shift of the belt from the loose to the tight pulley and the consequent starting of the cutting machine. matic, it being unnecessary for the operator to make any motions additional to the motion 01 shifting the workin the usual way toward and from the cutting mechanism between sewing operations.

The turntable support 4- may. have mounted thereon any suitable turn-table mechanism for holding the work, the specific character of such mechanism being immaterial to the present invention. It will sutfice to say that the work, which is in the form of a, flat sheet, is placedbetween the This action will be entirely auto- I upper and lower plates 28, 29 which are rotatably mounted on the support at so as to turn about a shifting center. The specific structure of the particular turn-table mechanism shown in Fig. 1. is fully disclosed in my said copending application.

Having thus set forth the nature of th invention, what I claimherein is: I

1. In combination, sewing mechanism, cutting mechanism spaced from the sewing mechanism, a work-holder shiftable from sewing to cutting position, and controlling means for starting and stopping the cutting mechanism connected to be operated by the shifting movement of the work-holder.

2. In combination, sewing mechanism, cutting mechanism spaced from the sewin mechanism, a work-holder shiftable from sewing to cutting position, a belt-shift for controlling the operation of the cutting mechanism, and means associated with said work-holder for automatically operating said belt-shift to start the cutting mechanism preparatory to the arrival of the work-holder in cutting position.

3. In combination, sewing mechanism,

cutting mechanism spaced from the sewing mechanism, a. work-holder shiftable from sewing to cutting position, a belt-shift for controlling the operation of the cutting mechanism, and a cam on said work-holder I and connections controlled by said cam for operating said belt-shift to start the cutting mechanism.

4;. In combination, sewing mechanism, cutting mechanism spaced from the sewing mechanism, a work-holdershiftable from sewing to cutting position, means for starting and stopping the cutting mechanism, and an actuating element assoclated' with the work-holder for operating said firstmentioned means to throw the cutting mechanism into operation preparatory to the arrival of the Work-holder in cutting position.

In testimony whereof, I have signed my name to this specification.

RUDOLPH BECKER.
